dt-bindings: fsi: Document the FSI controller common properties
Since there are multiple FSI controllers documented, the common
properties should be documented separately and then referenced
from the specific controller documentation. Add bus-frequency for
the FSI bus and CFAM local bus frequencies. Add interrupt
controller properties.
